A former walk-on with the Huskies in 2008, Amosa earned a scholarship in the team’s 2010 fall camp en route to becoming Washington’s starting fullback this past season. At his Pro Day in March, he ran a 4.93-second time in the 40-yard dash with 34 bench-press reps and 28 1/2-inch vertical.

A league source confirmed the 5-foot-11, 200-pound Walker’s signing as he joins fellow Redbird teammates, quarterback Matt Brown and linebacker Nate Palmer, in Green Bay. He concluded career at Illinois State as the school’s all-time leader in receptions (250), receiving yards (3,565) and receiving touchdowns (32).

Walker, who led the Missouri Valley Conference with 90 receptions, 1,319 receiving yards and touchdowns (nine), ran a 4.59-second time in the 40 with a 39-inch vertical. He had 16 games with over 100 yards receiving in college.

The Baltimore Sun’s Aaron Wilson is also reporting the Packers have signed Arizona State alumnus Brandon Smith, who's attempting a switch from wide receiver to cornerback following a collegiate career was mired by injury.

Smith, who finished with only 10 receptions for 196 yards and two touchdowns at ASU, had a brief stint with Seattle in 2011 preseason.

The Packers signed five tryout players last season, including wide receiver Jarrett Boykin who went on to make the 53-man roster and see action in 10 games.
